REASSEMBLY
1. w/o DIFFERENTIAL LOCK:
ASSEMBLE DIFFERENTIAL CASE
(a) Apply all of the sliding and rotating surfaces with gear oil.
(b) Install the 2 thrust washers and side gears. Using the table below, select the thrust washers which will
ensure that the backlash is within the specification.
Try to select washers of the same size for both sides.
Backlash: 0.02 − 0.20 mm (0.0008−0.0079 in.)
Thrust washer thickness
Thickness mm (in.)Thickness mm (in.)
1.60 (0.063)1.90 (0.075)
1.75 (0.069)2.05 (0.081)
(c) Install the side gears with the side gear thrust washers,
pinion gears, pinion gear thrust washers and pinion shaft.
HINT:
Align the hole for the pinion shaft and differential case hole.
(d) Using a dial indicator, measure the side gear backlash with holding the one pinion gear toward the case.
Backlash: 0.02 − 0.20 mm (0.0008 − 0.0079 in.)
If the backlash is not within the specification, install a thrust
washer of different thickness.
(e) Install the pinion shaft pin and washer.
Torque: 27 N·m (275 kgf·cm, 20 ft·lbf)

ion shaft pins.
Torque: 58 N·m (590 kgf·cm, 43 ft·lbf)
(k) Using a dial indicator, with holding the side gear and mea- sure the backlash.
Backlash: 0.02 − 0.20 mm (0.0008 − 0.0079 in.)
HINT:
Measure at all 4 locations.
If the backlash is not within the specification, install the thrust
washer of a different thickness. Thrust washer thickness
Thickness mm (in.)Thickness mm (in.)
1.60 (0.063)1.90 (0.075)
